So, I found a way to switch models in the main menu. However, the model does not read the texture. It does however read the alpha channel. In other words it is shiny and black and does not show the texture. As such I am asking if anybody ran into this problem before and knows the solution. I tried deleting the alpha channel and that made it invisible. An all white alpha channel makes the model all black. An all black alpha channel makes the texture shiny.
Note- The model I am switching is Sion to Revan. I don't know if that helps with the problem, but still.
